Subject: binwidth gen.
Подскажите, пожалуйста, перевод "The detection of modes requires a fine tuning of the binwidth". И еще как бы Вы перевели само это слово "binwidth"

From this histogram, one has the impression that the distribution of the diagonal is bimodal with peaks
at about 138.5 and 139.9. The detection of modes requires a fine tuning of the binwidth.
Using methods from smoothing methodology (Hardle, Muller, Sperlich and Werwatz, 2003)
one can find an "optimal" binwidth "h" for "n" observations.

When you make a histogram, you're essentially making a bar chart that shows how many data points fit within a certain range. That range is the bin width. For instance, suppose you were counting the number of questions that people answer on this site per hour. You might plot it as 1-5, 6-10, 11-15 and so on. In that case, your bin width would be 5 - every bar on your histogram represents a range of five questions. You could take the same data and plot it as 1-10, 11-20, 21-30 and so on. In that case, your bin width would be 10. Obviously, the larger you make your bin, the more detail you lose. The narrower the bin, the more you're sort of missing the point of a histogram.
